Looking for some 9.00R16 or 255/100R16 Michelin XL, XML, XCL, XZL, etc military tires. Basically a 36x10ishR16. Tall and narrow would work good for me right now.

Can't seem to locate these sizes. If I wanted to lift the truck and fit 38's I could get the bigger versions off of eBay for less than $500...but I don't want to lift it...won't fit in the garage if I do...

You can't really find them anymore. They stopped surplussing out the obsolete sizes about 6 years ago and they have dried up. People are starting to have dry rot and age issues with them now. The wider sizes the USMC currently uses occasionally pop up but not like they were several years ago.
